Actions and Spectrum 

Action: 

Keratolytic Action: salicylic acid is a keratolytic agent that helps break down and remove dead skin cells. It acts by softening and loosening the outer layer of the skin, allowing the shedding of dead skin cells and unclogging of pores. This action makes it effective in treating various skin conditions, particularly those involving excessive scaling, such as acne, warts and psoriasis. 

Anti-inflammatory Action: salicylic acid possesses mild anti-inflammatory properties. It helps to reduce redness, swelling, and irritation associated with various skin conditions. While its anti-inflammatory action is relatively weaker than other medications like corticosteroids, it can still relieve inflammatory skin conditions such as Seborrheic dermatitis.

Acne: salicylic acid is an effective compound that aids in the removal of debris from pores through its exfoliating properties and elimination of dead skin cells.

Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester. 

Category B: There were a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.   

Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.    

Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   

Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.

Pharmacology

Pharmacology:  

salicylic acid is a widely used topical medication that has various pharmacological effects on the skin. It is frequently employed to treat various skin conditions such as acne, psoriasis, warts, corns, calluses, and other dermatological issues. 

Pharmacodynamics:  

Keratolytic activity: drug works by softening and loosening the outer skin layer, which promotes the shedding of dead skin cells. This exfoliating effect helps to unclog pores, prevent the formation of comedones (blackheads and whiteheads), and improve overall skin texture. 

Anti-inflammatory effect: drug possesses mild anti-inflammatory properties. It can reduce redness and inflammation associated with as psoriasis and acne. However, its anti-inflammatory action is less potent than other medications like corticosteroids. 

Antifungal activity: drug also exhibits some antifungal properties, particularly against certain dermatophyte fungi, also treats fungal infections like tinea pedis (athlete’s foot) or tinea corporis (ringworm) when combined with antifungal agents. 

Pharmacokinetics: 

Absorption 

When applied topically, salicylic acid can be absorbed through the skin. drug can penetrate the stratum corneum (outermost layer of the skin) and reach the underlying tissues. 

Distribution 

The distribution of the drug extends to the deeper layers of the skin, encompassing both the epidermis and dermis. The extent of distribution depends on factors such as the formulation used and the characteristics of the skin. It is primarily localized in the treated area, and systemic distribution is minimal when used topically. 

Metabolism 

salicylic acid is metabolized mainly in the liver. It undergoes hepatic metabolism through two primary pathways: conjugation with glycine to form salicyluric acid (major pathway) and conjugation with glucuronic acid to form salicyl phenolic glucuronide (minor pathway).  

Excretion and Elimination 

Salicylic acid metabolites, primarily salicyluric acid and salicyl phenolic glucuronide, are excreted in the urine. Small amounts may also be excreted in the feces.

Adminstartion

Administration:  

Apply a thin layer: Use a clean applicator or your fingertips to apply a thin layer of salicylic acid to the affected area. Avoid applying it to unaffected areas or broken skin.

Wart removal: The drug is often used to remove common warts and plantar warts. By gradually softening and dissolving the thickened skin layers. 

Psoriasis and dandruff management: The drug can help reduce the scaling and flaking associated with conditions like psoriasis and dandruff. It helps remove the outer layer of skin cells and reduces the buildup of scales.
